A review of waste tyre pyrolysis : a discussion and analysis

Abstract

Abstract: Over the years, the prospective of end-of-life tyres as a source of fuel, a chemical feedstock and carbonaceous material through pyrolysis has been explored immensely. Through literature review evaluation and analysis, this paper aims to present and discuss the development of waste tyre pyrolysis process as well as the derived products with their possible application pathways. The various reactors that can be employed during the pyrolysis process are discussed. Furthermore, the different types of pyrolysis processes as well as their influence on product yield are highlighted. The paper drew the conclusion that the pyrolysis literature which has been continuously developed over the years emphasize the need to fully understand how operating conditions such as temperature, pressure, heating rate, retention time, feed size; material feed rate ; reactor selection and the type of pyrolysis influence the selection and optimization of product stream/s
